WATER-HEATING- SYSTEM.

Specification of Letters VPatent. Patented May 28, 1918.

Application led January 18,1917. Serial No. 143,176.

To all 'whom 'it may concern.' n

.Be it known that I, SAMUEL A. VVisNoM, a citizen o-f the United States, residing at San Mateo, in thecounty of San Mateo and State of California, have invented certain new. and useful, Improvements in Water- Heating Systems, of which the following is a specification. n l

This invention relates to a water heating system for gas stoves and the primary object of the invention is to provide ak system of pipes in communication with a storage'tank and connected to a water supply for heating the water through the medium of a gas stove whereby any burneu on the stove may be employed for heating the water.

One of the objects of the invention is to provide a plurality of coils of pipe associated with the various burners in a gas stove whereby the water in the system will be heated whether one, two, ork all, of the gas burners are in use. f f

As a further object of the invention the device is provided with means for employing the heat generated by the burners within the oven of the stove so that the water may be heated when either the gas plates at the top or the burners in the oven of the stove are in use.

A further object of the invention is to provide a heating system associated withv the gas burners of a gas stove that may be employed for heating the water Without detracting from the heat used for cooking puroses.

p A further object of this invention is the provision of a water heating system which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and the accompanying drawings, wherein is illustrated the preferred form of my invention, in which;

Figure 1 is a vertical section through a gas stove showing my invention applied thereto.

Fig. 2is a section on the line 2 2 of Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a section on the line 4.-4: of Figa la Referring to the drawing, wherein is illustrated the preferred form of my invention, and in which like numerals of reference indicate corresponding parts throughout the several views, the gas stove A is of the usual constructiony and includes the oven 1 having the bottom shelf 2 upon which cooking utensils may be rested and which receive the heat through the openings in the shelf in the usual manner. Below the shelf 2 the oven has a plurality of burners 3 which are connected to a gas supply pipe 4. i Disposed above the gas burners 3 land beneath the shelf 2 is an elongated coil 5 clearly shown'by Figa of the drawing. One end of the coil is connected to the water supply pipe and the opposite end is in communication with a Vboiler or `suitable hot water container. It is to be noted that'this coil covers the greater portion of the area of the oven 1 at the lower-part thereof. The gas burners 3 are usually all lighted together' when the oven is being used and, since the heat must pass upwardly from the burners and into the upper portion of the oven, it is obvious that the water within the coil 5 will be quickly heated. Furthermore the horizontal plane in which the coil 5 is disposed permits the heat to act upon a great quantity of water at one time.

At the top of the oven 1 is a partition 6 above which is arranged a plurality of gas burners 7 which are connected in the usual manner to a gas supply pipe 8. It will be understood, of course, that these gas burners are provided with the usual valve whereby the burners may be used independently of or simultaneously with each other. The top plate 9 of the stove is arranged considerably above the partition 6 while interposed between the top plate 9 and the partition 6 is a plurality of frusto-conical casings 10 one of which embraces the gas burners 7. The interior of each casing is in open communication with the heat ejecting opening in the top plate 9.

Arranged within each casing 10 is a spiral coil l1 constructed of water pipe and the lower terminal of each coil is in communication with a water supply pipe 12. The upper terminal of each coil is in communication with a second pipe 13 which is in communication with the storage tank or boiler (not shown). Each spiral coil 11, conforms substantially to the shapecf the frusto-conisal casing in which it is arranged. The

lowermost turn in each coil is approximately the diameter of the gas burners 7 while the uppermost turn of each coil is considerably smaller in diameter.

Each turn of each coilis7 therefore, disposed in the path of the heat as it is emitted from the flames of the burner when it passes up through the center of each coil. A comparatively large amount of water is thus quickly heated in each coil and the use of the gas burners 7 will serve to heat sufficient water whereby a supply can be maintained in the boiler at all times.` The shape and disposition of each coil does not interfere with ythe heat lemployed for cooking purposes.

From the foregoing it will be observed that a very simple and durable water heating system has been provided, the details of which embody the `preferred form. I desire it tov be understood however, that slight changes in the minor details of construction may bemade without departing from the spirit ci the invention or the scope ofthe claim hereunto appended.

l claim:

A heating system of the character described comprising a plurality of burners, a

truste-conical easing embracing each burner,

the top plate of the stove having an opening 3() charge end, a. supply pipe connected tothe 40 intake endsY of the coils, av return pipe connected to the discharge ends of the coils, the lowermost turn of each eoil being equal in diameter to the diameter of the burner, and the uppermost coil being approximately the diameter of the opening in the top of the casing whereby the flame from the said burner will rise directly toward the coils of pipe and toward the restricted end of the casing.

In testimony whereof I ailix my signature in presence of two witnesses.
